WINDMILL-RE GULATOR.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed May '7, 1907. Serial No. 372,396-

10 all whom it may concern:

Be it known that I, O'r'ro O. Honvnr, a citizen of the United States, residing at Ong, in the county of Clay and State of Nebraska, have invented a new and useful Windmill-Rcgulator, of which the following is a specilication.

This invention relates to regulator attachments for wind mills such as are utilized for hoisting water, and the object of the invention is to provide simple and efficient means whereby the wind wheel may be thrown out of gear automatically when the water in the tank to which it is forced reaches a predetermined level.

Another object is to provide means whereby the attachment may be relieved 9fsurplus pressure so as to prevent injury which might result therefrom.

Another object is to provide a regulator which can be readily adjusted to operate at any predetermined pressure.

A. still further object is to provide means for compressing air within the water tank or receptacle to enable the water to be discharged under pressure subsequent to its storage within the tank.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawing is shown the preferred form of the invention.

Said drawing is a View partly in section and partly in elevation of the complete apparatus.

Referring to the drawing by characters of reference, 1 designates a tower of any preferred proportions and which supports a tank 2 which is preferably sealed as shown and has a water inlet pipe 3 extending from the well 4 and a water outlet pipe 5. A float operated valve 6 is arranged within the tank and is designed to close the inlet whenever the water within the tank reaches a predetermined level. This valve is also preferably provided with a weight 7 so that it will open automatically when the water in the tank falls below a predetermined level.

A pump rod 8 extends downward in the usual manner from the wind wheel, not shown, and suitable means, not shown, is designed to be operated thereby for forcing water tln'ough the pipe 3 and into tank 2,

A cylinder 9 is connected preferably to the pump 10 and has an air inlet 11 which is normally closed by means of a spring pressed valve 12. A piston 13 is mounted to reciprocate within cylinder 9 and its red 14 has an arm 15 connected thereto and detachably secured in any desired manner to the rod 8 as shown at 16. An outlet pipe 17 extends from cylinder 9 and opens into the top of tank 2. It is to be understood that the arm 15 is normally disconnected from rodS and is only attached thereto when it is desired to get'a predetermined air pressure within the tank 2.

Suitably supported at a desired point, preferably above the platform 18 of the well 4 is a cylinder 19 the lower end of which is open. A piston 20 is mounted to reciprocate within the cylinder and has a rod 21 extending downwardly therefrom and through the open end of the cylinder. This rod is secured to a cross head 22 connected by means of rods 23 with another cross head 24 located above the cylinder 19. A wire or red 25 which is usually employed for throwing the wind wheel out of gear is connected to the cross head 24-. An auxiliary cylinder 26 is supported adjacent cylinder 19 and communicates therewith through two ports 27 and 28. A piston 29 is mounted to reciprocate within this auxiliary cylinder and its rod 30 extends downward through the open lower end of said cylinder and is pivot-ally connected to a lever 31. fulcrumed as at 32 and carrying an adjustable weight 33. A pipe 34 connects the upper end of cylinder 26 with pipe 3. A vent 35 is formed in the cylinder 26 in alinement with port 28 for the purpose hereinafter set forth.

The normal position of the pistons 20 and 29 is adjacent the upper ends of their respective cylinders and as the wire 25 is not under pressure it is obvious that the wind wheel will be free to rotate and'actuate the rod 8 so as to force water into the tank 2 through pipe 3. When the water within this tank reaches a predetermined level valve 6 will close and the continued operation of the pump will cause the water to be driven through pipe 34 and into cylinder 26. Piston 29 will therefore be pressed downward and expose the port 27 so as to permit the water to flow into cylinder 19 and press downward on piston 20. The wire 25 will therefore be pulled downward and the wind wheel thrown out of gear. As soon as the pressure upon piston 29 is relieved, as by the opening of the valve 6, the weight 33 will move it upward to its normal position and the water within cylinder 19, will be free to pass outward through port 28 and the bottom of cylinder 26. The wind wheel upon being relieved of restraint in this'manner will be promptly thrown into operation and again actuate the pump, whereupon the operation described will be repeated. Should the pressure upon the piston 29 be unusual or sudden said piston will be driven downward a suificient distance to expose the vent 35 through which a portion of the water will be free to escape. A desired air pressure may be maintained within the tank 2 by connecting arm 15 to rod 8 so as to cause the actuation of the air pump for as long a period as desired. By forcing air into the tank in this manner the same can be usedfor expelling water therefrom to desired elevations above the tank. Of course where a sealed tank is not used the air pump will be dispensed with. Importance is attached to the fact that the rods of the pistons 20 and 29 work through the open ends of the cylinders. It becomes unneccssary therefore to use packing for said rods and, as a result, friction is reduced to the minimum.

What is claimed is:

1. A. regulator for wind mills and the like comprising a regulator cylinder having an inlet and an outlet port, a piston mounted to reciprocate within said cylinder, means for connecting a regulating wire to said piston, an auxi iary cylinder communicating with the regulator cylinder through the ports thereof, a weight controlled piston within the auxiliary cylinder and disposed to close either of said ports, and means for directing water under pressure into the auxiliary cylinder to actuate the piston therein.

2. A regulator of the character described comprising a cylinder having an inlet and an outlet port, a piston mounted to reciprocate therein, means for connecting a regulating wire to the piston, an auxiliary cylinder communicating with the lirst mentioned cylinder through said ports. a weight controlled piston mounted within the auxiliary cylinder and disposed to close either of the ports, said cylinder having a vent, and lneans for directing Iiuid under pressure against said piston, said piston being normally interposed between the vent and the fluid inlet.
